UNITED STATES PATENT OEEICEO CHESTER W. SYKES, OF SUFFIELD, CONNECTICUT.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 50,749, dated October31, 1865.

To all whom it may concern:

Be it known that I, CHESTER W. SYKES, of Suffield, Hartford county,State of Connecticut, have invented certain Improvements in Plows; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanyingdrawings, and to lettersof reference marked thereon.

In the drawings, Figure 1 is a plan view of my improved plow. Fig. 2 isa side View.

. Fig. 3 is another side view with the parts differently arranged. Fig.4 is a rear end view of Fig. 3. 4

The object of this invention is to obtain a plow which may be readilyand easily changed irom a right to a left hand plow-that is, themold-board may be on the right or left hand side in relation to thelandside of the share. The advantages arising from such an arrangementare that the land is all turned in one direction, thus avoiding deadfurrows, and also in thc operation it can be used entirely on one sideof the field, for on reaching the end of the furrow the mold-board maybe turned to the other side of the share, and a newl furrow be cutalongside the one just left. In this manner much time is saved usuallyoccupied in going' from one side of the field to the other.

I will now more particularly describe the construction and operation ofmy invention.

A is the share or land side of the share, formed in one piece with thebeam B. To this part A the handles a a are attached at the rear end. Tothe top of this share A, l hinge the double mold-board C, at b and c.This mold-board is of peculiar form, which lI will hereinafter morefully describe.

D is a brace, attached by the joint f at its rear end to the piece g,between the handles a a', and at its frontend tothe mold-board C by theball-andsocket joint h. The part E of this brace is jointed to the ballh at one end and at the other is pivoted to the part F of the brace. Thereason for making this part E in this form is that it may pass freelyfrom side and not strike the rear end of the moldboard, as shown at Fig.3, and also when the brace is brought down, as in Fig. 2, it forms aspring, which gives under pressure and allows the knee-j oint l to beclosed, thus straightening the brace and fastening the board in positionfor entering the furrow.

The upper part, G, of the hinge c is of peculiar shape, as shown in Fig.4, and is formed in this way that when the mold board is turned toeither side the part 7c of this brace G may strike against the share A,and thus forni a brace to keep out the rear end of the incid-board.

The operation of this invention is simple. It consists in unfasteningthe mold-board by raising the brace D, thus allowing the moldboard to beturned to the opposite side. This being donc, the brace I) is presseddown, fastening it there, as before mentioned.

In order to more easily enter the ground and more eftectually turn overthe ground raised by the share, I make the mold-board C of peculiarshape, as I before mentioned, which I will now describe. In shape itconsists ot' a segment of the surface of a cone, and it isv hung on theshare A in such a manner that a center line, which would pass throughthe center of the base and t-he apex of the cone, if

produced, is not horizontal, but inclines from the front to the rear,and in order to accomplish this I cut the front edge on an angle, asshown at on, Fig. 1, so that it may lit up to the share at n, which itwould not otherwise do if hung in the manner described. The object ot'this is, as before mentioned, that the plow may more easily cntcr theground, and also, by bringing the upper edge ofthe moldboard lower down,more completely turning the ground thrown up by the share.

I do not wish to confine myself to exactly the form of mold-board beforedescribed, but, if desirable, may use a cylindrical one instead ofconical, similarly arranged.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent,is

l. In combination with the other parts of a plow, a mold-board hung onthe top of a share in sucha manner that itunay be moved from side toside and fastened, substantially in the manner and for the purposedescribed.

2. The peculiar form of the mold-board C, substantially as herein setforth.
